General • Do not use the motor (gearhead) and driver beyond its specifications, or injury or damage to equipment may result. • Keep your fingers and objects out of the openings in the driver, or fire or injury may result. • Do not touch the motor (gearhead) and driver during operation or immediately after stopping. The surface is hot

and may cause a skin burn(s).

Installation • To prevent the risk of damage to equipment, leave nothing around the motor and driver that would obstruct

ventilation. • Do not hold the motor (gearhead) output shaft or cable. This may cause injury. • Do not touch the motor output shaft (key groove or pinion) with bare hands. Doing so may result in injury. • When assembling the motor with the gearhead, exercise caution not to pinch your fingers or other parts of your

body between the motor and gearhead. Injury may result. • Securely affix the motor (gearhead) and driver to their respective mounting plates. Inappropriate installation may

cause the motor/driver to detach and fall, resulting in injury or equipment damage. • Provide a cover over the rotating parts (output shaft) of the motor (gearhead) to prevent injury. • When installing the motor (gearhead) in the equipment, exercise caution not to pinch your fingers or other parts of

your body between the equipment and motor or gearhead. Injury may result. • Securely install the load on the motor (gearhead) output shaft. Inappropriate installation may result in injury.

Operation • Do not shut off the negative side of the power supply during operation. Also, note that the wiring for the power

supply does not disconnect. Doing so may cause damage to equipment. • Provide an emergency stop device or emergency stop circuit external to the equipment so that the entire equipment

will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury. • Immediately when trouble has occurred, stop running and turn off the driver power. Failure to do so may result in

fire, electrical shock or injury. • Do not touch the rotating part (output shaft) during operation. This may cause injury. • The motor surface temperature may exceed 70 °C even under normal operating conditions. If the

operator is allowed to approach the running motor, attach a warning label as shown below in a conspicuous position. Failure to do so may result in skin burn(s).

Warning label

Disposal • To dispose of the motor (gearhead) and driver, disassemble it into parts and components as much as possible and

dispose of individual parts/components as industrial waste.

3 Precautions for use

−5−

3 Precautions for use This section covers limitations and requirements the user should consider when using the product.

• Regeneration energy When using the motor in operation such as vertical drive (gravitational operation) or sudden starting/stopping of a inertial load, regeneration energy may generate. Since the driver has no function to consume regeneration energy, if the output capacity or overvoltage allowance of the DC power supply is small, the protective function for the power supply or driver may activate and the motor may stop. When performing these operations, use a DC power supply or battery that has a large output capacity or overvoltage allowance. Also, use an electromagnetic brake motor not to drop the moving part in vertical drive (gravitational operation). If protective function for the power supply or driver is activated, contact your nearest Oriental Motor sales office.

• Do not use a solid-state relay (SSR) to turn on/off the power A circuit that turns on/off the power via a solid-state relay (SSR) may damage the motor and driver.

• Conduct the insulation resistance measurement or withstand voltage test separately on the motor and the driver. Conducting the insulation resistance measurement or withstand voltage test with the motor and driver connected may result in injury or damage to equipment.

• Grease measures On rare occasions, a small amount of grease may ooze out from the gearhead. If there is concern over possible environmental damage resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively, install an oil pan or other device to prevent leakage from causing further damage. Oil leakage may lead to problems in the customer’s equipment or products.

• Apply grease to the output shaft of a hollow shaft flat gearhead If you are using a hollow shaft flat gearhead, apply grease (molybdenum disulfide grease, etc.) on the surface of the load shaft and inner walls of the hollow output shaft to prevent seizure.

• Preventing electrical noise Provide noise elimination measures to prevent a motor or driver malfunction caused by external noise. For more effective elimination of noise, use a shielded I/O signal cable or attach ferrite cores if a non-shielded cable is used. Refer to p.19 for the noise elimination measures.

• Note on connecting a power supply whose positive terminal is grounded The driver's main power supply input terminal (CN1), I/O signal connector (CN3), communication connector (CN5/CN6/CN7) and control power supply input terminal (TB1) are not electrically insulated. When grounding the positive terminal of the power supply, do not connect any equipment (PC, etc.) whose negative terminal is grounded. Doing so may cause the driver and these equipment to short, damaging both.

• The driver uses semiconductor elements. Handle the driver with care. The driver uses parts that are sensitive to electrostatic charge. Before touching the driver, turn off the power to prevent electrostatic charge from generating. If an electrostatic charge is impressed on the driver, the driver may be damaged.

• Use an extension cable (supplied) when extending the wiring distance between the motor and driver

• When installing a load, do not damage the motor output shaft (gearhead output shaft) or bearing. Forcing in the load by driving it with a hammer, etc., may break the bearing. Do not apply any excessive force to the output shaft.

• Do not modify or machine the motor (gearhead) output shaft. The bearing may be damaged or motor (gearhead) may break.

Output shaft shape

• Combination type parallel shaft gearhead A key groove is provided on the output shaft of each combination type parallel shaft gearhead. Form a key groove on the load side and affix the load using the supplied parallel key.

• Round shaft type A flat section is provided on the motor output shaft of each round shaft type. Apply a double-point screw, etc., at the flat section to securely affix the load and prevent it from spinning.

How to install a load

• Using a coupling Align the centerline of the motor (gearhead) output shaft with the centerline of the load shaft.

• Using a belt Adjust the motor (gearhead) output shaft to lie parallel with the load shaft and form right angles between the output shaft/load shaft and the line connecting the centers of both pulleys.

• Using a gear Adjust the motor (gearhead) output shaft to lie parallel with the gear shaft and allow the output shaft to mesh correctly with the centers of the gear teeth.

• When using the output axis tip screw hole of a gearhead Use a screw hole [M6; Effective depth 12 mm (0.47 in)] provided at the tip of the output shaft as an auxiliary means for preventing the transfer mechanism from disengaging.

6.9 Installing the driver The driver is designed so that heat is dissipated via air convection and conduction through the enclosure. Install the driver on a flat metal plate having excellent vibration resistance and heat conductivity. When two or more drivers are to be installed side by side, provide 20 mm (0.79 in.) and 25 mm (0.98 in.) clearances in the horizontal and vertical directions, respectively.

Note • Install the driver in an enclosure whose pollution degree is 2 or better environment, or whose degree of protection is IP54 minimum.

• Do not cover the radiation vent of the driver. • Do not install any equipment that generates a large amount of heat or noise near the driver. • If the ambient temperature of the driver exceeds 40 °C (104 °F), revise the ventilation condition

or force-cool the area around the driver using a fan.

Installing with screws Affix the driver through the mounting holes using two screws (M4: not supplied).

6.11 Installing and wiring in compliance with EMC Directive The BLV Series is designed and manufactured for use as an internal component of equipment. The EMC Directives require that your mechanical equipment in which the BLV Series is installed satisfy the applicable requirements. The installation/wiring methods of the motor and driver explained here represent the basic methods that are effective in helping your mechanical equipment conform to the EMC Directives. The final level of conformance of your mechanical equipment to the EMC Directives will vary depending on the control system equipment used with the motor/driver, configuration of electrical parts, wiring, layout, hazard level, and the like. Therefore, you must conduct the EMC tests on your mechanical equipment to confirm compliance.

Applicable Standards EMI Emission Tests EN 61000-6-4, EN 61800-3 C3EMS Immunity Tests EN 61000-6-2, EN 61800-3 C3

Effective measures must be taken against the EMI that the BLV Series may give to adjacent control-system equipment, as well as the EMS of the BLV Series itself, in order to prevent a serious functional impediment in the machinery. The use of the following installation and wiring methods will enable the BLV Series to be compliant with the EMC Directive.

Connecting a mains filter • Install a mains filter in the power line in order to prevent the noise generated within the driver or control system

from propagating outside via the DC input line. • When using a power supply transformer, be sure to connect a noise filter to the AC input side of the power supply

transformer. • For a mains filter, use MC1210 (TDK-Lambda Corporation) or equivalent product. Install the mains filter as close

to the AC input terminal of DC power supply as possible. • Connect the ground terminal of the mains filter to the grounding point, using as thick and short a wire as possible. • Use a shielded cable of AWG18 to 14 (0.75 to 2.0 mm2) for the AC input cables and output cables.

Use cable clamps and other means to secure the AC input cables and output cables firmly to the surface of the enclosure.

• Do not place the AC input cable parallel with the mains filter output cable. Parallel placement will reduce mains filter effectiveness if the enclosure's internal noise is directly coupled to the power supply cable by means of stray capacitance.

Wiring the power supply cable and signal cable • Use a shielded cable of AWG16 to 10 (1.25 to 6 mm2) for the power supply cable, and keep it as short as possible. • Use a shielded cable for the I/O signals cable, and keep it as short as possible. • Strip a part of the shielded cable and ground the stripped part using

a metal cable clamp that contacts the stripped cable around its entire circumference, or use a drain wire to make the ground connection.

• Attach a cable clamp as close to the end of the cable as possible, and connect it as shown in the figure.

Cable clampShielded cable

6 Installation

−20−

Notes about installation and wiring • Connect the motor, driver and other peripheral control equipment directly to the grounding point so as to prevent a

potential difference from developing between grounds. • When relays or electromagnetic switches are used together with the system, use mains filters and CR circuits to

suppress surges generated by them. • Keep cables as short as possible without coiling and bundling extra lengths. • Wire the power lines such as the motor cable and power cable away from the signal cables by providing a

minimum clearance of 100 mm (3.94 in.) between them. If they have to cross, cross them at a right angle. Place the AC input cable and output cable of a mains filter separately from each other.

• Use a supplied extension cable when extending the wiring distance between the motor and driver. The EMC measures are conducted using the Oriental Motor extension cable.

Precautions about static electricity Static electricity may cause the driver to malfunction or suffer damage. While the driver is receiving power, handle the driver with care and do not come near or touch the driver. Always use an insulated screwdriver to adjust the driver's potentiometers or switches.

Note The driver uses parts that are sensitive to electrostatic charge. Before touching the driver, turn off the power to prevent electrostatic charge from generating. If an electrostatic charge is impressed on the driver, the driver may be damaged.

Note • For the driver's power supply use a DC power supply with reinforced insulation on its primary and secondary sides.

• When connecting, check the indication of the driver case and pay attention to the polarity of the power supply. Reverse-polarity connection may cause damage to the driver.

• Do not wire the power supply cable of the driver in the same cable duct with other power line or motor cable. Doing so may cause malfunction due to noise.

• When cycling the power or plugging/unplugging the connector, turn off the power and wait for the POWER LED to turn off.

• When unplugging the CN1 connector, do so after pressing the lever (orange) on the CN1.

Input signals The signal state represents the "ON: Carrying current" or "OFF: Not carrying current" state of the internal photocoupler rather than the voltage level of the signal.

• FWD input and REV input When the FWD input is turned ON, the motor turns in the clockwise direction according to the time set by the acceleration time potentiometer. When the FWD input is turned OFF, the motor stops. When the REV input is turned ON, the motor turns in the counterclockwise direction according to the time set by the acceleration time potentiometer. When the REV input is turned OFF, the motor stops. If both the FWD input and REV input are turned ON, the motor stops instantaneously.

• STOP-MODE input Select how the motor should stop when the FWD input or REV input is turned OFF. When the STOP-MODE input is ON, the motor stops according to the time set by the deceleration time potentiometer. STOP-MODE input is OFF, the motor stops instantaneously.

Note When the electromagnetic brake motor is used for vertical drive (gravitational operation), be sure to stop the motor after turning the STOP-MODE input ON. If the motor is stopped while the STOP-MODE input is OFF, the moving part may drop.

• M0 input Select how the motor speed is set. When the M0 input is ON, the motor turns at the speed set by the external potentiometer or external DC voltage. When the M0 input is OFF, the motor turns at the speed set by the internal potentiometer. By switching the M0 input, the motor can be operated at two speeds through use of both the external potentiometer and internal potentiometer. Refer to p.32 for details. You can set a maximum of eight speeds by changing the assignments of M0 to M2 inputs using the OPX-2A.

• ALARM-RESET input This input resets the present alarm that the protective function of the driver was actuated. To reset each alarm, be sure to remove the cause of the alarm before switching the ALARM-RESET input. To reset an alarm, turn both the FWD input and REV input OFF, remove the cause of the alarm, and then turn the ALARM-RESET input ON (and keep it ON for 10 ms or more). The ALARM-RESET input will not be received if the FWD input or REV input is ON. If the alarm cannot be reset with the ALARM-RESET input, cycle the main power. If a control power is used, also cycle the control power.

• MB-FREE input This input signal is used with electromagnetic brake types. Select how the electromagnetic brake would operate when the motor stops. If the MB-FREE input is ON, the electromagnetic brake will be released. If the MB-FREE input is OFF, the electromagnetic brake will actuate and hold the shaft in position.

Note The MB-FREE input is not accepted while an alarm is present.

Output signals The signal state represents the "ON: Carrying current" or "OFF: Not carrying current" state of the internal photocoupler rather than the voltage level of the signal.

• SPEED-OUT output 30 pulses are output with each revolution of the motor output shaft synchronously with the motor operation. The pulse width of output pulse signals is 0.2 ms. You can use the SPEED-OUT output to calculate the motor speed.

To display/monitor the speed of the motor output shaft or reduced speed of the gearhead output shaft, connect an accessory digital speed indicator SDM496 (sold separately). See p.47 for details.

• ALARM-OUT output When the driver’s protective function actuates, the ALARM-OUT output turns OFF and the ALARM LED blinks (normally closed). In the case of a standard type, the motor stops naturally. In the case of an electromagnetic brake type, on the other hand, the motor stops instantaneously, upon which the electromagnetic brake actuates and holds the shaft in position. To reset an alarm, turn both the FWD input and REV input OFF, remove the cause of the alarm, and then turn the ALARM-RESET input ON (and keep it ON for 10 ms or more). The ALARM-RESET input will not be received if the FWD input or REV input is ON. If the alarm cannot be reset with the ALARM-RESET input, cycle the main power.

Using a controller with a built-in clamp diode If a controller with a built-in clamp diode is used, a leakage path may form and cause the motor to operate even when the controller power is off, as long as the driver power is on. Since the power capacity of the controller is different from that of the driver, the motor may operate when the controller and driver powers are turned on or off simultaneously. When powering down, turn off the driver power first, followed by the controller power. When powering up, turn on the controller power first, followed by the driver power.

8.3 Setting the acceleration time and deceleration time You can set the acceleration time and deceleration time for starting and stopping. The acceleration time and deceleration time are effective for all speed settings. The acceleration time and deceleration time are same value. It cannot be set individually. Set the acceleration/deceleration time using the acceleration/deceleration time potentiometer (VR2). Turning the potentiometer clockwise increases the time. Acceleration time refers to the time needed for the motor to reach the rated speed (3000 r/min) from the stationary state. Deceleration time refers to the time needed for the motor to stop from the rated speed (3000 r/min).

11 Inspection

−43−

11 Inspection It is recommended that periodic inspections be conducted for the items listed below after each operation of the motor. If an abnormal condition is noted, discontinue any use and contact your nearest office.

During inspection • The motor/gearhead mounting screws are not loose. • Check for any unusual noises in the motor's bearings (ball bearings) or other moving parts. • The bearing (ball bearing) and gear meshing parts of the gearhead are not generating noise. • The motor/gearhead output shaft is not misaligned with the load shaft. • Are there any scratches, signs of stress or loose driver connections in the cable? • The openings in the driver are not blocked. • The driver mounting screws and power connection terminal screws are not loose. • Are there any strange smells or appearances within the driver?

Note • Conduct the insulation resistance measurement or withstand voltage test separately on the motor and the driver. Conducting the insulation resistance measurement or withstand voltage test with the motor and driver connected may result in injury or damage to equipment.

• The driver uses semiconductor elements, so be extremely careful when handling them. Static electricity may damage the driver.

12 Protective function

−44−

12 Protective function When an alarm generates and the driver's protective function is actuated, the ALARM-OUT output will turn OFF. In the case of a standard type, the motor stops naturally and once the motor has stopped, the motor output shaft becomes free. In the case of an electromagnetic brake type, on the other hand, the motor stops instantaneously, upon which the electromagnetic brake actuates and holds the shaft in position. At the same time, the ALARM LED will start blinking. The cause of the alarm can be checked by counting the number of times the ALARM LED blinks.

Blinking pattern example: Sensor error (number of blinks: 3)

0.3 s0.3 s 1.5 s

1 2 3 1 2 3

To reset an alarm, be sure to remove the cause of the alarm and then perform one of the following operations: • Turn the ALARM-RESET input ON for at least 10 ms. (Refer to p.24 for details.) • Cycle the main power.

If a control power is used, also cycle the control power.

Note • Alarms cannot be reset if the FWD input or REV input is ON. Be sure to stop the motor before resetting any alarm.

• Alarms caused by damage to the motor or driver itself cannot be reset using the method explained above. Please contact your nearest office.

• Make sure the ALARM-RESET input remains ON for at least 10 ms. If the ON period is too short, the alarm may not be reset.

• The undervoltage alarm is released automatically when the driver main power supply voltage exceeds the undervoltage detection level. If the FWD input or REV input remains ON status, the motor will rotate concurrently with releasing the alarm.

• If an external stop alarm generates, the motor stops instantaneously.
